i5 vs. i7 13" cMBP heat and fans

I've searched high and low on the forums so please don't throw rocks at me.

I'd like to purchase a 13" cMBP as I just prefer the power and lack of scroll lag over the rMPB that I encounter frequently on the websites that I use. Also, some of the same sites are still not retina optimized thus the text is quite blurry.

So once and for all, does the i7 on the 13" cMBP run hotter than the i5 and do the fans kick on more? I would have about 8 tabs open and streaming data at the same time.

The i7 will be more powerful than the i5. That being said, it will be able to handle more such as in the event of multitasking. Your computer will only heat up depending on what you throw at it.

The i7 and i5 dual cores are very similar CPUs, with the same TDP, cache, and really differ only in clock speed. I wouldn't expect to see much difference in heat buildup.

That said, I don't have a 13" rMBP. I do have the 15", with the current middle CPU (2.7GHz), and the fan kicks in maybe once a week unless I'm gaming. It's the only laptop I've ever used that's completely silent during normal use. And it has a 45W quad core. If they can get that so thoroughly right, I can't imagine the 13" model being any worse.
